Is this too much boat for a single person to handle at launch? (It comes
with the basic stock trailer.)

Very easy with a little practice.


Is it realistic to tow with a 4-cylinder Toyota 2wd truck? (It weighs 1,040
pounds.)

Get the owner's manual for the truck, it will tell you the towing
capacity. It's boat weight plus trailer weight. Don't violate the
capacity, you'll run out of brakes and overheat the transmission.


Will regulations governing 2-cycle engines force an engine replacement in a
couple years? A replacement engine could easily cost more than a replacement
boat!

The existing two-strokers will be grandfather in.
